Making: Making a Soapy Water Bottle

Placeholdertive
Make a low-cost soapy water bottle that students can take home and leave near the family latrine.

Time
20 minutes

What You Need

 * One empty and clean plastic 1.5 litre water bottle for each child.
 * 30 g of detergent powder per child (plus extra for spillage)


 * That is, about 1.5 kg. for 40 students
 * A funnel for every few students.


 * You can make a few funnels of paper beforehand. See Appendix.
 * Something that will poke a hole in the lid of the plastic bottle.

​Preparation
You can make a few funnels of paper beforehand. See Appendix.

Activity

 * Poke a hole in the lid of each plastic bottle.
 * Have each student:

​Explain
 * Measure 30 g of laundry soap – about two heaping spoonfuls.
 * Use the funnel that is being passed around the class to put the soap in the bottle.
 * Fill the bottle mostly with water.
 * Cover the hole on top of the bottle and shake

<p style="margin-bottom:0in">Ask
 * <p style="margin-bottom:0in">You have now made soapy water good for washing hands!

<p style="margin-bottom:0in">Explain
 * <p style="margin-bottom:0in">Where is a good place to leave the soapy bottle? 
 * <p style="margin-bottom:0in">Students should reply: Near the latrine or where we eat.

<p style="margin-bottom:0in">Warning: Some students may start to squirt the soapy water as a game. Have students agree the water is just for washing hands.
 * <p style="margin-bottom:0in">Please bring the soapy bottle home and tell your parents: 
 * <p style="margin-bottom:0in">This soapy bottle is perfect to leave by the latrine. 
 * <p style="margin-bottom:0in">It is cheaper to refill the bottle with two big spoonfuls of detergent than to purchase a bar of soap, and it works great. 
 * <p style="margin-bottom:0in">After you use the soapy bottle, you can tell your hands are clean because they remain a little slippery.
